Background: Herpes simplex virus type 1 (HSV-1) is a common virus in human. The rate of drug resistance is increasing in HSV-1. In this study, anti-viral effects of Rhus coriaria L. fruit extract was evaluated against acyclovir resistant HSV-1 before, during and after the infection of Hela cell line.
Materials and methods: In this experimental study, the trypan blue and 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide (MTT) tests were used to rule out the potential toxic effects extract on the Hela cell line. Antiviral effects of the extract on acyclovir resistant HSV-1 were evaluated before the infection and at different concentrations of the extract. The effective minimal cytotoxic concentration was assessed at different times of virus replication after virus adsorption. Virus titer was determined by tissue culture infectious dose 50 (TCID50) method.
Results: The CC50 value and effective minimal cytotoxic concentration were determined at 780 µg/ml and 390 µg/ml respectively. Treatment of HSV-1 with extract resulted in 1 log10 TCID50 reduction in virus titers after 3 and 4 hour. The highest reduction in acyclovir resistant HSV-1 infectivity was obtained 2 and 4 hour after the infection of the cells with virus resulting in 1.7 log10 TCID50 reduction as compared with control.
Conclusion: The antiviral effects of Rhus coriaria L. fruit extract on acyclovir resistant HSV-1 after virus infection was more remarkable than the treatment of virus with the extract before virus adsorption.
Keywords: Sumac extract, Antiviral effects, Herpes simplex virus type 1.
Masoud ParsaniaEffects of Avicennia marina fruits aqueous and hydro alcoholic extract on streptozotosin –induced diabetic male ratshttp://iau-tmuj.ir/browse.php?a_id=1212&sid=1&slc_lang=en
Background: Diabetes mellitus is a major endocrine disorder and growing health problem in most countries. We studied effects of Avicennia marina fruits aqueous and hydroalcoholic extract in the diabetic rat by streptozotocin.
Materials and methods: In this experimental study, 45 male rats were divided into 9 groups of 5, including sham group, diabetes sham, positive sham (diabetes + 0.9% normal saline) and treated diabetic groups orally with aqueous and hydroalcoholic extract of Avicennia marina fruits (30, 60, 120 mg/kg daily for three consecutive days). Twenty-four hours after the last treatment rats, blood samples were collected from heart for determining the blood glucose and insulin concentration levels using glucose oxidase and enzyme-linked immunosorbent assay (ELISA) methods respectively.
Results: All doses of Avicennia marina fruits aqueous and hydroalcoholic extract significantly decreased serum glucose level of diabetic test rats compared to treated diabetic sham rats. 60mg/kg of Avicennia marina fruits hydroalcoholic extract and all doses of Avicennia marina fruits aqueous extract significantly increased serum insulin level of diabetic test rats compared to treated diabetic sham rats.
Conclusion: In this study, we have shown that Avicennia marina fruits aqueous and hydroalcoholic extract can significantly decrease the blood glucose.
Keywords: Avicennia marina, Diabete, Blood glucose, Insulin.
Liela KamaeiComparative analysis of the effects of honey and nano silver particles on blood biochemical factors in renal stone of male micehttp://iau-tmuj.ir/browse.php?a_id=1213&sid=1&slc_lang=en
Background: Honey, as the most curative material, is used for healing majority of diseases. This study aimed at analyzing the role of honey and silver nano particles in changing blood biochemical factors in renal stone of male mice.
Materials and methods: In this experimental study, 30 Albino male mice were randomly divided into 5 groups of 6 each, including healthy control, negative control received only water with 1% ethylen glycol, and 3 experimental groups received 15 ethylen glycol and 125mg/kg honey, 250 mg/kg honey and 125 ppm nano silver, respectively. After 30 days treatment, blood sampling was done via heart, and blood urea nitrogen (BUN), creatinine, and albumin were evbaluated.
Results: The findings showed that only in the group of 125 mg/kg honey, significant decrease and increases could be found in the amount of BUN (p<0.05) and ALB (p<0.05), respectively. However, compared to negative control group, there was not seen any significant difference in group of nano silver particles. Additionally, nothing was reported regarding the effects of these 3 groups on creatinine.
Conclusion: It can be expected that honey, due to its strong antioxidant properties, will result in improvement of blood biochemical factor in kidney stone, while silver nano particles will cause increase in urine calcium oxalate and consequently lead to renal stone.
Keywords: Albumin, Blood Urea Nitrogen, Creatinine, Honey, Renal stone, Nano silver.
Hossein SazegarAssessment of vitamin D efficacy on treatment of symptoms of patients with peripheral diabetic neuropathy admitted to Amiralmomenin Hospital in Tehran in 2015http://iau-tmuj.ir/browse.php?a_id=1214&sid=1&slc_lang=en
Background: Few studies have investigated the relationship between vitamin D deficiency and diabetic neuropathy. Present study aimed to investigate the effect of vitamin D in the treatment of diabetic peripheral neuropathy.
Materials and Methods: In this semi-experimental trial, 30 diabetic subjects aged over 35 years with peripheral neuropathy with serum levels of vitamin D less than 30ng/ml, were sequentially selected. The NSS questionnaire (Neuropathy Symptom Score) used to determine the severity of the symptoms of diabetic neuropathy (subjective data) and NDS questionnaire (Neuropathy Disability Score) used for symptoms of neuropathy (objective information). Participants were treated by 50,000 IU/week of oral vitamin D for 10 weeks.
Results: 30 patients with mean age of 60.1 years, including 10 (33%) men, were studied. 83.3% had serum vitamin D deficiency (under 20ng/mL) and 16.7% had serum vitamin D insufficiency (20-30ng/mL). Mean (± standard deviation) serum vitamin D levels was 14.37±5.86 ng/mL. Seventy percent of participants showed a significant decrease in NSS scores (p=0.02), as well as declining in mean of their scores (p<0.05) before and after the prescription of vitamin D. By contrast, there seems to be no significant changes in NDS scores at that interval (p=0.748).
Conclusion: Prescription of vitamin D for 3 months improved the symptoms of diabetic neuropathy in diabetic patients regarding NSS; however, NDS showed no changes in the examinations of participants.
Keywords: Vitamin D, Peripheral neuropathy, Diabetes.

Payam RoshanfekrCross validation of artificial intelligence and mathematical relationships in the diagnosis of iron deficiency anemia and thalassemia in screening centers of northern Iran in 2014 http://iau-tmuj.ir/browse.php?a_id=1218&sid=1&slc_lang=en
Background: Traditional methods for discrimination iron deficiency anemia (IDA) and β-thalassemia trait (BTT), which using CBC indices, are not accurate enough and complementary tests such as Hb electrophoresis are time consuming and expensive. In this study, we introduced the methods with higher accuracy.
Materials and methods: In this study, 510 CBC samples were collected from several screening centers in north of Iran. The number of samples associated with IDA, BTT, and normal subjects were 167, 132, and 211, respectively. The collected samples were used to establish the methods, adaptive neuro fuzzy inference system (ANFIS) and multi-layer perceptron (MLP), through the use of 10-Fold cross validation. In each step of cross validation mathematical methods such as MI, E&FI, S&BI, S&LI, G&KI, EI and SI were investigated by the test samples.
Results: Several indices, such as sensitivity (SENS), specificity (SPEC), positive predictive value (PPV), negative predictive value (NPV), accuracy (ACC), and Youden’s index (YI), have been obtained for the all mentioned methods in each step of Cross Validation. T test showed that the ANFIS and the MLP had not difference (p<0.05). The mathematical methods had not difference (p<0.05), but there was difference between AI-based and Math-based methods (p<0.05).
Conclusion: This study indicates that using artificial intelligence as medical diagnostic tools can help the physicians in discrimination between similar diseases and also it increases accuracy in difficult cases.
